The registered nurse is discussing care of an infant diagnosed with a patent ductus arteriosus (PDA) with a nursing student. The registered nurse determines that the nursing student needs further teaching regarding a PDA when the student states that which circulatory change is a characteristic of this disorder?
This shunting allows oxygenated and unoxygenated blood to mix.
Blood is shunted to the right side of the heart.
This shunting results in increased pulmonary blood flow.
Blood is shunted to the left side of the heart.
The Correct Answer is D
A. "This shunting allows oxygenated and unoxygenated blood to mix."
Explanation: This statement is correct. In PDA, the shunting of blood between the aorta and pulmonary artery allows oxygenated and unoxygenated blood to mix, leading to decreased oxygen saturation in the systemic circulation.
B. "Blood is shunted to the right side of the heart."
Explanation: This statement is correct. In PDA, blood is shunted from the left side of the heart (aorta) to the right side of the heart (pulmonary artery).
C. "This shunting results in increased pulmonary blood flow."
Explanation: This statement is correct. PDA leads to increased pulmonary blood flow as a result of the shunting of blood from the aorta to the pulmonary artery.
D. "Blood is shunted to the left side of the heart."
Explanation:
A patent ductus arteriosus (PDA) is a congenital heart defect where the ductus arteriosus, a fetal blood vessel that normally closes shortly after birth, remains open. In PDA, blood is shunted from the aorta (left side of the heart) to the pulmonary artery (right side of the heart), resulting in increased pulmonary blood flow. Therefore, the correct statement is that "Blood is shunted to the right side of the heart."
